警 告

以下程序(方法)可能带有攻击性,仅供安全研究与教学之用。使用者风险自负!
Full path disclosure (WASC-13):
 

 

 
?skin=1
 
Directory Traversal (Windows) (WASC-33):
 
?widget_id=2&skin=1\1
 
DT allows to read only css-files (in folder /skins/ and subfolders). At
turned off mq it's possible to use Null Byte Injection, which allows via DT
to read arbitrary files.
 
XSS (persistent XSS) (WASC-08):
 
Three persistent XSS holes. For attack it's needed to bypass protection
against CSRF (parameter savewidgets). E.g. using reflected XSS.
